The closure according to the invention has the advantage that it may behandled with a maximum of ease and rapidity by existing known automaticbottle sealing mechanisms.

The invention consists in a bottle closure cap of the kind havingreleasing means associated with a bottle closure cap comprising asubstantially loop-like formation of wire or like suitable materialwhose two extremities are engaged beneath the gofferings and a cork orlike insert piece of the closure cap, in which the two extremities liealong exterior grooves of the closure cap Anism ofVcharactercommonly"inuse. k' i LIfA desired, 'the twoextremitiesfmay'be' 'engaged betweerrth'e 'cork'insert *piece* and themetal Lcap, w or between the'corkinsert fpecefand-an interi60 mediatelining as'f'of paper 'located"between cork -Closure kcaps jassociated'with :releasing means contemplated'by "the invention' are sunken orin-A "dented as 'in conformity wwith "the`-coniigur"a'tion L05 'of Ytheisaid"releasingnieans whi `:h-latter' 'are :'d'e'- signed 'to "-be':bent 'and --lsnugly received "by and "'ne'sted in 'the lsaid sunken or-indented capupon its upper surface and so that the said releasing"means may in no "way obtrude or *interi ere "with 'WD '.ithefreepassageof thecap (with'relea'sing-fmeans "i fitted 'or' incorporated)faong Ythe feedrchuterand l directly into the ltlfiroat'oxvrnouth of"and intoan `readily understood reference-willnowabemade yto "theaccompanying drawingxwherein "like 4reference .numerals :denote J likeparts "throughout the several viewswhichare as iollovv 1 v ,Figure '.1lis a perspective view Aof" oner designiof 'metal 'closure cap before*being 'formed and Afitted according to' the invention withf associatedreleasingmeans.

It may b e here noted as important that during `-the` normal act ofsealing a bottle 'mouth with a closure cap of the crown cork typethegoffering or crimped skirt portion of the latter is pressed inwardly,and when so applying according to the present invention a closure capandits associated cap releasing `means the said inward pressure causes thesaid' releasing means to be slightly raised away from the sunken vcapsurface or indentation 14 so to be `1n ready positionV forinsertion of ahandkerchief or the' like 424 or rever 25 (see Figure 1o of thedrawing). l

l By the use of the invention while there is secured a maximum ofsealing efliciency, damage by chipping of bottle necks due to removal ofthe closure caps therefrom is entirely eliminated; and n bottleclosure'caps-are associated with releasing means for each 'of thesame inmanner so that the composite article so formed may be quite conveniently.handled by the sameautomatic bottle sealing mechanisms whichjare vatpresent in use for handling crown seal-bottle closures of knownconventional type; l Y Y Within the spirit of the invention as describedand claimed herein,there may be employed *mod ifications in regard toshape, design andl dispot sition of cap indentations or caplreleasingmeans. along exterior `grooves formedA by the gofferings i Y What Iclaim isz-j ,l p i i 1.
